The invention relates to a method for achieving a retrievable reshaping of the hair. According to the invention, a preparation containing at least one first active ingredient or active ingredient complex is applied to the hair. Said preparation alone or in combination with other substances can give the hair a shape-memory effect once it has been applied to the hair and has undergone the inventive treatment. The preparation also contains at least one second active ingredient, which is a cationic substance. The hair is given a specific (permanent) style and said permanent style is fixed by inducing a chemical or physical modification to the applied active ingredients. After a desired or undesired deformation of the memory shape, the original memory shape can be reproduced by a physical stimulation. In addition to the permanent hairstyle, a second (temporary) style can be imprinted. The invention also relates to a method for reproducing a previously programmed, permanent hairstyle, which has been temporarily reshaped or deformed in another manner into a temporary style.

Als Maß zur Beurteilung der Formgedächtniseigenschaften einer Zusammensetzung kann der Memory-Faktor dienen, in welchem sowohl die Umformbarkeit einer permanenten Frisurenform in eine temporäre Form (Formfaktor) als auch die Rückstellung der permanenten Form aus der temporären Form (Rückstellfaktor, Wiederherstellungsgrad) berücksichtigt werden. As a measure to assess the shape memory properties of a composition of Memory factor may serve, in which both the formability of a permanent hairstyle into a temporary shape (form factor) as well as the recovery of the permanent shape from the temporary shape (restoration factor, degree of recovery) are taken into account.Wird von einer glatten Strähne ausgegangen, auf die eine Lockenform als permanente Form aufgeprägt wird und auf die anschließend eine zweite, glatte Form als temporäre Form aufgeprägt wird, so kann der Formfaktor bestimmt werden nach folgenden Kriterien: If starting from a smooth strand to which a curly shape has been impressed as permanent shape and onto which a second, smooth shape has been impressed as a temporary shape, the form factor can be determined according to the following criteria:

Der Rückstellfaktor kann bestimmt werden nach folgenden Kriterien: The reset factor can be determined according to the following criteria:
